In Sweden March 4, 1937 3 Claims.

The present invention relates togauges for indicating the level in liquid receptacles of the type having float-operated index-means. The invention is particularly suited for combination with the fuel reservoir of petroleum-stoves, petroleum-lanterns and the like but may also be applied in other connections.

The object of the invention is to provide a simple gauge of the type referred to, having float-operated index-meanswhich may be easily mounted in the reservoir and likewise may easily be removed if desired, for example, for adjusting purpose. Another object of the invention is to provide means to facilitate the application of the index-means in proper position in the reservoir and to maintain said means in such position after it has been applied.

With the above-mentioned and other objects in view, the invention consists in a gauge comprising a member to be removably applied in. an opening in the wall of the reservoir, a position securing tongue or lap provided on said member, and index means carried by said tongue or lap. The invention consists also further in the novel and simplified construction, and parts, combinations and arrangements of parts, as hereinafter more particularly described and set forth in the accompanying claims.

The invention will be described hereinafter with reference to the accompanying drawing in Which Fig. 1 is a part sectional view in elevation showing the indicating or gauging apparatus as a whole inserted in the wall of the reservoir,

Fig. 2 is a front view of the member and floatoperated index-means removed from the reservoir,

Fig. 3 is a plan view of the index-disk or dial,

Fig. e is a side elevation of the float-operated index-means shown in Fig. 4, and

Fig. 5 is a plan view showing the portions surrounding the opening in which the index-means is to be applied.

With reference to the drawing, I designates the top wall of the fuel reservoir, for example, of a petroleum lantern and 2 a collar or tube which is secured on the wall I of the reservoir by soldering or any other suitable means. The angular lever 3 is pivoted by meansof a pin 4 to a member inserted removably in the collar or tube 2 and consisting of a disk 5 which is received in the opening of the collar, and of an integral tongue or lap 6 projecting downwardly from the edge of the disk and in the lower part of which the pin 4 is rotatable. The lever 3 carries a float 1 at one end thereof, the other end thereof being formed as a pointer, and to this effect extends through a slot 8 in the disk 5. The lower end of the tongue 6 carrying the pin 4 is bent inwardly to such an extent that the terminal of the pointer will move substantially along a diameter of the circular disk as the lever turns about the pin. The edge of the portion surrounding slot 8 is provided with a scale graduated in a suitable manner and permits the position of the pointer to be read. The disk 5 thus forming a dial abuts on a circumferential shoulder 9 in the opening of the collar 2, and said shoulder is broken at one point or provided with a recess H! in which the top portion of the tongue 6 is extended thus securing the disk in a definite angular position. The disk is further held against the flange by means of an annular washer II which is pressed against the disk by the screw threaded cover [3 having a glass I2. A suitable sealing annulus l4 consisting, for instance, of soft india rubber may be provided in the cover for sealing purpose. Such annulus may be arranged on both sides of the glass.

The index-means consisting of the dial 5, float 1, lever 3 and carrying means 6, 4 may be removed as a unit from the reservoir, for example, for adjusting purpose. Said unit may be easily set in proper position in the reservoir, the tongue 6 serving as guide means at the insertion thereof in the recess l0 formed at the periphery of the opening.

The lever may be formed as an angular lever having the pivot pin 4 positioned at the apex of the angle but it may also be straight in which case the collar and disk having the scale may be applied to a vertical wall of the reservoir. Further modifications of the detailed construction may also be performed within the scope of the invention.

What I claim is:

1. In gauges for indicating the level in liquid reservoirs, the combination of a tube mounted in the reservoir, a support member mounted removably in said tube, a tongue provided on said member, float-operated index-means carried by said tongue, and a recessed seat in the tube for receiving said tongue to fix the angular position of the member and the index-means in the reservoir.

2. In gauges for indicating the level in liquid reservoirs, the combination of a tube mounted in an opening in the wall of the reservoir, a dial member mounted removably in said tube, an integral tongue on said dial member, a recessed 10 thereof, the other end forming a pointer extending through a slot in the dial, a pin pivoting the lever to the tongue, a tube associated with the: reservoir, a laterally recessed shoulder in said tube for receiving said tongue, whereby the dial and index means carried thereby may be easily mounted as a unit in correct position in the reservoir to seat on the shoulder with the tongue in said recess.
